He was riding off road (probably over the NE/East side of Brighton as he lives that way) was found at about 10 but no one's sure how long after the accident that was. She thinks he must have gone over the bars judging by his injuries. He was wearing a helmet which is wrecked.

Ambulance staff shouldn't have taken the bike as they can't secure them in the Ambulance, in case they are involved in a road accident.
If they did anything with it they would have been wise to note it in their paperwork, the hospital has a copy.
The police would be more likely to look after the bike as the crew would concentrate on getting your mate to hospital.

when I was going to work the other morning, through a smallish village there was a fella fast asleep, or I hope he was asleep and nothing worse, he was right on a T junction, he was lucky he hadn't be run over, there had been a carnival the day before and I guess the drink and the sun got the better of him, police had just arrived as I drove past, I hope he was ok although I bet he had an hang over from hell

funny enough I had to go though a town centre at about 5 the other morning, I couldn't believe what a state it was in, drunk people, empty bottles, cans, fast food boxes, It was a right old mess, went back later that afternoon and full of shoppers and "normal people" and it was so clean, the council do an good job IMO

when i was at uni i had a mate wake up impaled on railings on london road with a punctured lung. he`s not sure what happened but was on a bike at the time so these accidents do happen. still bloody crazy/scary though.

Sounds like he may have been very lucky, if he'd had the same otb in the woods who knows how long he may have lain there, perhaps he had a fall and then got himself to the road, does he remember anything ?
